Have kids bring in 100cans or something similar, and after you've reached thegoal, you can recycle them. If you want to take the project one step further, make agarbage pizza, as shown here. This model shows thecomposition of American landfills by the percentage ofvarious types of trash. Kids bring in the various "pizzatoppings," and you glue them onto the pizza.
